About this product


  • A small laser module capable of delivering a visible green beam
  • Used in the manufacture of presenter pointers, laser pens, tools and lighting effects
  • 532nM wave length

Product overview

• A small laser module capable of delivering a visible green beam
• Used in the manufacture of presenter pointers, laser pens, tools and lighting effects
• 532nM wave length
• Working voltage is 3Vdc
• Less than 300mA current consumption
• 0.3-0.85mW power output

CAUTION: This device generates a visible beam of green light that will not burn or cut. However, it is moderately hazardous and should not be viewed by the naked eye on the same axis as the beam.

Rated 5 out of 5 by from Perfect for my needs I bought this to mend a simple laser pointer and it works brilliantly. I connected it to two 1.5V batteries and a switch and I am very happy how powerful and bright it is, especially at at long distances. I can see this has potential for use in many other creations & devices and I would buy again.

Rated 5 out of 5 by from A brilliant little laser that is still the cheepest around. Price has proven useful due tragic misreading of power needed to power it

Operating Specifications



The leads are black and white. Which one needs to be connected to the +ce terminal of the supply? Or doesn't it matter?

Is the beam produced a continuously visible line or just a dot? (ie would it be suitable to demonstrate refraction through glass for second level physics students?)

Can this be used for continuous operation? If not, what is the maximum recommended run time?

Asked by: TheRealMe
The datasheet does not state a max run time, so we would say it is continous, however cooling may be needed. https://maplindownloads.s3-eu-west-1.amazonaws.com/N02KH-Datasheet-7522.pdf
